Subject: [PATCH v2 3/4] mac80211: add rate control support for encap offload
Date: Fri, 28 May 2021 14:05:43 +0800 [thread overview]
Message-ID: <d447c18f07fe3dc7092f5502de3e35e6b7ae69e1.1622164961.git.ryder.lee@mediatek.com> (raw)
In-Reply-To: <2176023d8f13d82d093452e1c105609396c30622.1622164961.git.ryder.lee@mediatek.com>
The software rate control cannot deal with encap offload, so fix it.
